"Let's see what we get from a different angle."

I brought up the other security camera feeds in the museum. Using the different cameras Dick and I were able to trace the projection beam of the illusions to their source.

"There," I said, pointing at a statue of a Greek man in toga. "See the eyes? They're glowing."

I brought up another angle, this one facing the back of the statue. The new angle showed two faint glowing beams emitting from the eyes. The beams went all the way out to where the holographic woman appeared. Facing the same view as the projector, she looked flat and thin. A 2D rendering of what everyone else saw as 3D. 

"We need to find out how whoever did this was able to install those projectors into the statue."

Three days worth of security footage rolled across my monitor at breakneck speeds. The threat warning software was activated to help us identify any strange or unusual goings on at the museum prior to the robbery. The computer finally binged four days prior to the crime. I stopped the rewind and Dick and I watched the footage play out. We didn't see anything at first. 

"There," said Dick.

The floor and air around the statue seemed to ripple with movement. It was hard to see, but it was there. The strange ripple in the scenery took up the shape of an adult male. Seemingly invisible to the guards and everyone in the gallery, the shape climbed over a velvet rope hung up around the statue and went to work.

"Another illusions," I said softly. "This one probably mounted on the prep's body, showing the surrounding area to make it appear like he's invisible. But if he can make himself invisible... why the need for the elaborate show a few days later?"
